Crystal structure and Hirshfeld surface analysis of 1,3,3,4,4,5,5-hepta-fluoro-2-(3-[(2,3,3,4,4,5,5-hepta-fluoro-cyclo-penten-1-yl)-oxy]-2-{[(2,3,3,4,4,5,5-hepta-fluoro-cyclo-penten-1-yl)-oxy]meth-yl}-2-methyl-prop-oxy)cyclo-pentene

In the title compound, C(20)H(9)F(21)O(3), a central sp (3)-hybridized carbon atom is decorated with three hepta-fluoro-2-meth-yloxy(cyclo-pent-1-ene) arms and a methyl group. The primary packing is determined by C-F⋯F-C inter-actions, forming [001] chains, which are consolidated via weaker C-F⋯F-C and C-H⋯F-C contacts. A Hirshfeld surface analysis was conducted to aid in the visualization of these various influences on the packing: this revealed that the largest contribution to the surface contacts arises from F⋯F inter-actions (53.5%), followed by F⋯H/H⋯F (34.5%) and F⋯C/C⋯F (7.1%).
